Definitions
- the invention relates to a distance determination method by means of a camera sensor according to the preamble of claim 1 and a distance determination system according to the preamble of claim 19.
- WO 2008/080951 discloses a driver assistance system which determines, for example by means of a radar or lidar sensor, a distance to a vehicle in front.
- a camera is provided which detects the vehicle ahead and adapts the orientation of the distance sensors to the respective situation.
- an exact alignment of the distance sensors is only possible if the camera and the distance sensor are mounted either at the same height in the vehicle or by triangulation, if the distance of the camera to the vehicle ahead is known. For this reason, the de ⁇ fernung the camera is estimated from the leading vehicle based on the camera image, according to WO 2008/080951.
- the requirement for the accuracy of Entfer ⁇ voltage specifications may it be small, however.
- DE 10 2007 048 809 A1 describes a method and a device for detecting hidden objects in the roadway. . Crow. In this case, determines a position determination system using various sensors, such as GPS module, radar sensor, Lidarsensor or stereo camera, the position of the own vehicle and the positions of adjacent vehicles. By using a stereo camera, both an object recognition and a comparatively exact Entfer ⁇ voltage measurement without the use of additional distance sensors. Further, a vehicle towing vehicle communication system is disclosed, which transmits the environment information detected by the own vehicle to neighboring vehicles so that they can not detect view ⁇ bare objects themselves. For each transmitted object, there are a number of attributes that are either determined by the sensor or are called from a look-up table from ⁇ . The vehicle-to-vehicle
- Communication system also received vehicle parameters of the own vehicle such as the vehicle length, the driving ⁇ generating wide and the vehicle type.
- the object of the present invention is therefore to propose a method and a system which, without the use of separate distance sensors, enable a reliable and substantially exact distance measurement to a target object.
- the distance determining method of the invention by means of a camera sensor accordingly, a distance of the camera sensor to a target object be ⁇ agrees on the basis of a camera Informa ⁇ tion, is characterized in that the camera in ⁇ formation to a spatial extent of the area covered by the target object on a light sensor in the camera sensor region - sums up.
- the advantage of this process is that use is made of a directly captured by the camera Informa ⁇ tion, namely the spatial extent of the object on the light sensor for determining the distance ⁇ .
- no separate distance sensor such as a radar or
- Lidar sensor needed Since a plurality of current vehicle already equipped with a camera sensor, may ⁇ to the inventive method for determining the distance without any additional cost and manufacturing effort a multi ⁇ number of driver assistance systems, such as implements an intelligent speed and distance control.
- the camera information including the spatial extent of the area covered by the target object on ei ⁇ nem light sensor in the camera sensor region, is linked with information about the actual spatial He ⁇ stretching of the target object.
- the camera sensor is a mono-camera sensor. Since only a camera information about the spatial extent on the light sensor is required for determining the distance according to the invention, no second camera, as in a stereo camera sensor, is necessary. A known, but relatively cumbersome From ⁇ was intended by the balance of the images of two individual cameras in a stereo camera sensor is thus avoided.
- the use of a monocamera sensor instead of a stereo camera sensor also reduces the manufacturing ⁇ effort and thus the production costs.
- the camera sensor is a stereo camera sensor.
- the process can also be carried out in a stereo camera sensor without ⁇ sharmlichen effort.
- a method known per se for determining the distance is carried out by means of the stereo camera sensor and validated by means of the method according to the invention, and vice versa.
- the camera information comprises the spatial extent of the area covered by the target object on the light sensor in the camera sensor along a horizontal. The distance determination is thus performed across the width of the target object, which has the advantage that, as a rule, if the target object as example ⁇ a Car, the largest in the direction of travel detectable expansion is used for distance determination. The inevitably associated with each measurement of a physical quantity relative inaccuracy is thus particularly low.
- the camera information comprises the spatial extent of the area covered by the target object on the light sensor in the camera sensor along a vertical.
- the distance determination is additionally or alternatively Runaway ⁇ leads over the height of the target object. Unless it is the target object is a truck, whose spatial height is usually greater than its hoffmli ⁇ che width, thus a more accurate Abstandsbe ⁇ humor can be performed.
- the camera information comprises an area of the area covered by the target object on the light sensor in the camera sensor.
- the covered on the light sensor area can be easily determined, as a rule, example ⁇ , by counting the capped sensor cells in a CCD sensor.
- the covered area provides additional ⁇ In formation about the target object, which, for example allows a review of the means of the width of the target object and / or the height of the target object specified distance. Thus, an and validation of the distance information via one and the same sensor.
- the information about the actual spatial extent of the target object encompasses the spatial extent along the horizontal and / or along the vertical and / or the cross-sectional area of the target object.
- the light sensor is a CCD sensor chip (charge coupled device) or a CMOS sensor chip (complementary metal oxide semiconductor).
- CCD sensor chip charge coupled device
- CMOS sensor chip complementary metal oxide semiconductor
- the camera information it is advantageous for the camera information to include the number of detector lines covered by the target object on the CCD sensor chip (charge coupled device) or the CMOS sensor chip (complementary metal oxide semiconductor) and / or the Number of detector columns covered by the target object in the camera sensor on the light sensor chip and / or the number of total covered detector cells.
- a measure of the width, the height and the area of the covered area can be detected in a simple manner by counting the detector columns, detector rows or the individual detector cells.
- a ratio of the extensions along the horizontal and the vertical and / or the total covered area is formed from the spatial extent of the region covered by the target object on the light sensor. This allows determining charac ⁇ rule extension ratios for different types of targets and thus a further gain in information about the target object
- the target object of an object class is zugeord ⁇ net by means of the ratio of the extensions.
- the assignment to an object class allows a more detailed identification of the target object and thus einherge ⁇ starting the possibility to access charac ⁇ teristic of this object class, actual spatial extents for the calculation ⁇ voltage of the distance, provided that they are not transmitted directly from the target object.
- the method is characterized in that the object class classifies the target object as belonging to one or more of the following classes: vehicle brand, vehicle model, pedestrian or cyclist.
- vehicle brand a substantially accurate identification or classification of the target object and thus to an individual in Wesent ⁇ slotting to an object class.
- essentially individual actual syndromemli ⁇ che extents of the target object provided they are not transmitted directly from the target.
- an additional camera ⁇ information includes a direction of movement of the target relative to the camera sensor.
- the detection of the movement direction relative to the camera sensor allows a determination of the spatial orientation of the target object relative to the camera sensor.
- the information about the spatial orientation relative to the camera sensor offers the advantage that a width detected in the light sensor is recalculated with a non-identical orientation of the target object and the camera sensor, which can be adjusted to the width with identical orientation.
- an orientation other than the following vehicle with a camera sensor which are determined the actual spatial width entspre ⁇ sponding covering the light sensor.
- an additional Informati ⁇ on about the target object comprises the movement direction of the target object relative to the camera sensor and / or position information of the target object, wherein the position information is based into ⁇ particular on a global navigation satellite system.
- the additional information can be transmitted, for example, directly from the target object to the distance-determining vehicle.
- the position information on the target object can also be transmitted from the target object and allows a check ⁇ fied by the inventive method distance, with an exact verification is not possible, since the position determination using global navigation satellite systems in comparison to the inventive method with a relatively large inaccuracy is. The recognition of a distance in the range of several meters and thus safety relevant wrong distance is still possible.
- the information about the actual spatial extent of the target object and / or the additional information about the target object is detected by means of vehicle-to-X communication.
- the vehicle-to-X communication exchanges information on the basis of at least one of the following types of connection: WLAN connection, in particular according to IEEE 802.11,
- WLAN connections allow, for example, a high REMtragungsra ⁇ te.
- ISM connections offer a lower data transmission rate, but also allow data to be transmitted around a visual obstruction.
- ISM connections offer a lower data transmission rate, but also allow data to be transmitted around a visual obstruction.
- Infrared connections again offer a low data transfer rate ⁇ which is also severely limited in the absence of sight.
- mobile connections are not affected by obstructions and provide a good data transfer rate. But the connection is relatively slow.
- driver assistance systems which perform, for example, braking interventions or einregeln a distance to the preceding vehicle by means of acquisition of Mo ⁇ gate control, are supplied without additional distance sensors with the required distance to the execution information.
- driver assistance systems which, if necessary, issue a warning to the driver when a safety-critical minimum distance is undershot.
- This exemplary enumeration of driver assistance systems is not complete and can be expanded as desired since the determined distance can be made available to each driver assistance system and to each vehicle system.
- the information about the actual spatial extent of the target object and / or the additional information about the target object is validated by means of a comparison with the camera information and / or the additional camera information.
- a validation by means of the camera sensor can be carried out before processing the information or additional information acquired, for example, by means of vehicle-to-X communication. Since the camera sensor according to the method according to the invention is used anyway for distance determination, a validation without the involvement of other sensors is thus possible. For example, since no absolute actual extents can be measured on the light sensor, the ratio of extents on the light sensor can be compared to the ratio of actual spatial extents transmitted by the target.
- the information about the actual spatial extent of the target object is validated.
- the direction of movement of the target relative to the camera sensor can be detected directly by this.
- a validation of the additional information about the target object is possible.
- a Zielobj ekterkennungs- algorithm of the camera sensor, a detection threshold down ⁇ sets when the target object has already been assigned by means of the information about the actual spatial extent of the target object of an object class.
- the present invention further relates to a distance determination system which determines a distance of a camera sensor to a target object and which in particular carries out the method according to the invention for distance determination.
- the system comprises a camera sensor and a vehicle-to-X communication device and / or an electronic memory device and is characterized in that the camera sensor detects a camera information which comprises a spatial extent of the region covered by the target object on a light sensor in the camera sensor.
- an object class matrix is stored on the electronic memory device, which contains ratios of extensions along the horizontal and the vertical and / or the total covered surface of a multiplicity of different object classes.
- the system according to the invention has the possibility, with ⁇ means of an adjustment of the ratios of the extensions of the areas covered on the light sensor with the areas on the electronic memory device stored ratios of extensions to assign a target object of an object class.
- the assignment to an object class is thus independent of any object class possibly received via vehicle-to-X communication or actual extensions received via vehicle-to-X communication.
- the distance determination can also be carried out when the target object either does not transmit necessary for determining the distance information or the distance determination vehicle receives no entspre ⁇ sponding information, for example because it does not have a vehicle-to-X-communication.
- FIG. 3 shows a traffic situation in which the distance determination method and distance determination system according to the invention are used.
- Fig. La is shown an exemplary and schematic exporting ⁇ approximate shape of the inventive method.
- the camera sensor 1 which comprises the light sensor 2 and the optical lens 3.
- Light sensor 2 and optical lens 3 are arranged at a distance 8 from each other.
- the vehicle 4 is the ⁇ art is oriented such that camera sensor 1 detects the rear view of the vehicle. 4
- the rear view of vehicle 4 has a horizontal extent 5 in the horizontal, which corresponds to the vehicle width.
- Via beam path 6, an extension 7 is generated on light sensor 2, which indicates the width of the covered area on light sensor 2.
- Example ⁇ according to spatial extent 5 of vehicle 4 is known.
- the distance from the vehicle 4 to Kame ⁇ rasensor 1 is determined according to, for example by means of a simple geo ⁇ metric relationship.
- the example according to geometrical is ⁇ connexion shown in Fig. Lb.
- Length 10 corresponds to distance 8 in Fig. La
- Length 11 corresponds He ⁇ extension 7 on the light sensor 2 and length 11' corresponds to the vehicle width 5.
- FIG. 2 shows camera sensor 1 with light sensor 2.
- camera sensor 1 detects the rear view of vehicle 13.
- Spatial extensions 14 and 15 along the horizontal and the vertical are proportionally imaged onto light sensor 2.
- the ratio becomes formed on the light sensor 2 proportional extensions 14 and 15 formed.
- a ratio value is now sought which corresponds to the ratio value formed from extension 14 and extension 15. The result is a match with the ratio for a truck.
- Vehicle 13 is thus recognized as a truck due to the ratio sei ⁇ ner extensions 14 and 15 of camera sensor.
- Fig. 3 shows driving ⁇ convincing 16, spaced apart on the road track 19 follows vehicle 17th
- Both vehicles have, for example, vehicle-to-x communication devices. Since road track 19 has a cam, vehicles 16 and 17 are oriented in under ⁇ Kunststoffliche directions. Camera sensor 1 detects spatial extent 18 of the vehicle 17. Due to the un ⁇ ter Kunststoff orientations of the vehicles but does not meet extension 18 the width of vehicle 17, but a diagonal of the vehicle 17. By means of the vehicle to x-communication devices receives vehicle 16 inter alia the actual length and width of vehicle 17.
- transmitted vehicle 17 according to the example also its direction of movement.
- vehicle 16 initially determines the relati ⁇ ve orientation of both vehicles to each other.
- the back-calculated extension allows the determination of extraneous did ⁇ distance between vehicle 16 and vehicle 17th
- the diagonal 18 detected on the basis of the relative orientation of both vehicles and the camera sensor 1 is recalculated to the extent of the vehicle length to the light sensor 2.
- the distance between the two vehicles according to the example over the length and not over the width of vehicle 17 be ⁇ true.
- only vehicles 16 are provided with a vehicle-to-x communication device, but not vehicle 17.
- Vehicle 16 thus receives neither information about the orientation of vehicle 17 nor information about the actual spatial extent of vehicle 17.
- Camera sensor 1 recognizes, however, based on lane markings 20 that vehicle 17 is in a curve.
- ⁇ game according to the relative orientation of the vehicle 17 to vehicle 16 is determined by the orientation of Fahrbahnmarkie ⁇ stanchions 20 by, it is assumed that the vehicle follows lane 17 nineteenth Furthermore, an average ratio of vehicle width to vehicle length is assumed for vehicle 17, in order to keep a possible error in the distance determination on average as low as possible.
- there is sufficient information in vehicle 16 in order to determine the distance to the vehicle 17 by means of the area covered by the diagonal 18 on the light sensor 2.
- camera sensor 1 can directly detect the vehicle width of the vehicle 17th Once the width of vehicle 17 has been detected, this information can be used in later curves for exact distance determination without having to resort to average values of ratios of vehicle widths to vehicle lengths.
